During a visit with Chinese President Xi Jinping in 2015, Biden wore a dress by Vivienne Tam, a Hong Kong-born, New York City-based designer.
The designer told South China Morning Post that Biden gave Tam creative freedom to dress her for the event.
"At the end, she said, 'Just choose the pieces that best represent the brand and Vivienne Tam.' She really placed her trust in me, asking me to decide — and that was a fantastic feeling and experience to have," Tam said.
Tam also dressed the then-second lady for a state dinner at the White House.
